Design and Development of Simulation System for Mineral Process toward Plant-wide Optimization

For the logistics of mineral process is an organic link between various sectors,it is very important to the simulation study of logistics operations for optimal operation and control.Toward plant-wide optimization,to simulate the plant-wide logistics and production of mineral process and to study the effect of the operation and control of each unit process to the plant-wide performance,the overall framework of the simulation model is established based on the principle of the material balance and the conservation of mental.A simulation system for the logistics of mineral process is designed and developed,where includes the structure and function of the software and hardware platform,and the communication interface with the control and optimization system.This system emphasizes on the logistics simulation and the effects of operation and control to the plant-wide performance(i.e.,metal recovery rate,concentrate grade and yield,etc.)and provides a foundation for plant-wide optimization.The experiment is carried out on the proposed simulation system and the results show its effectiveness.
